EDGAR VJ. MYERS, OF SAN FRANCISCO, CALIFORNIA.

MACHINE FOB SCOURING PULP 0R PULVEEIZED ORE AND THE LIKE.

Application filed June 23,

To all whom i:/; may concern:

Be it known that l, EDGAR lV. Marlins, residing at San Francisco, countyof San l 'rancisco, State of California, a citizen of the United States,have invented. certain new and useful Improvements in lilachines lorSecuring Pulp or Pulverized Ure and the like, of which the following isa specification.

The object of my invention is the provision 01" simple and highlye'l'licient apparatus for scouring ground ore, or other material in agranular or pulverized state, and to this end my invention consists inthe apparatus construct .d substantially as described by or comingwithin the scope or meaning of the claim which follows this speciliotion.

In the drawings:

Fig. 1 is a view partly in side elevation and partly in section 01"apparatus embody ing my invention;

Fig. 2 is a to plan view of one of the units;

3 is a bottom plan View thereof.

T he apparatus shown in the drawings consists of a series of aligningsimilar units, 10, each having a longitudinal passage, 11, extendingfrom end to end, through which the pulp, or material to he treated,passes, and which passage is conical, or tapers, with its small endtorminrr the discharge or outlet, and a steam nozzle, 12, that sprayssteam into the chamber in the direction of: trarel of the pulp throughthe chamber, the pulp being thus p: ed in succession. from one unittothe no; a. finally discharged from the last one oil: the series. Nearthe inlet end 01 each unit is a battle, in the form of a diametricallyextending bar, 13, upon which the incoming; pulp strikes and by which itis spread or scattered and thrown by the force of the steam against theinner sides of the passage; and preferably, the steam nozzle is integraltherewith, extending clownwardly therefrom at the center of the passage.The baffle bar is hollow to form a pipe for the passage of steam to thenozzle, the bar opening being; in communication outside the unit, with abranch pipe, 14, that con- 1921. Serial No. 479,901.

nects with a steam pipe line, 15. Each branch pipe has a valve, 16, tocontrol the steam supply to the nozzle oi each unit.

To the top or first unit of the series is attached a hopper, 17, and tothe bottom or est one is attached a discharge nozzle, 18, for connectionwith a bin or other apparatus to which the scoured pulp is to l edelivered.

Each unit, at top and bottom has anges, 19, by which the adjacent unitsmay he bolted together, and by which the hopper, 1'7, and nipple, 18,maybe bolted to the first and last units of the series, the hopper andnipple having flanges for the purpose.

I do not confine myself to any particular number of units. One may beused, or, as shown in the drawings, a number may he used. Nor do Irestrict mysel'l to the den. ls of construction shown and described, thescope of the protection I seek not being limited to what is shown anddescribed, but to wnat is comprehended within the subjoined claim.

The steam spray puts the pulp in violent motion with the result that theparticles strike against the side walls of the unit, thus resulting inan effective scouring action, which. action is promoted by the expension of the particles from the heat imparted by the steam. lheconverging sides ot' the passage promote the scouringnction by bringingthe particles together as they approach the place of discharge from theunit,

lVh at I claim is:

pparatus ot the character described, comprising a member with a passagefor material to be treated, means to throw the material with forceagainst surfaces within the passage comprising a nozzle for deliveringfluid under pressure into the material going through such passage, and abattle in the passage from which said nozzle extends,

the baffle having an opening leading to the nozzle from a source ofsupply ot'fiuid exterior to the member.

In testimony whereof I hereunto a'fiix signature.

EDGAR Vi. ll LYERS.
